A periodic Cold Reboot (Battery Out, wait 15-30 sec, Battery Back in) will be the first place to start. But you might also want to delete some of the unused languages and other items that take up memory but you dont use. This can be done by unchecking the language support in the Apps Loader in Desktop Manager and using that to delete them from your Pearl

This happened to me last night, I couldn't see any of my recent calls or sms texts. I watched my phone closely and would see the new message icon then it would disappear. I looked around and saw my memory was ZERO. I pulled the battery and voila memory is back. I just bought my pearl 3 days ago. The version is v4.2.0.64

There are several ways to get more memory on your Pearl. One thing to do is to remove any Language support for those languages you don't use. This can be done by using the desktop manager Applications loader and unchecking any language you don't need.

Let us know if there is anything else we can do to help with this problem or your BB.

whats worse is my phone is critical to me today to communicate with my freinds and family while i am at work on christmas, and tmobile closes their customer service???? awful, might have to return this and stick with verizon

I have been having the same problem with my 8100 Pearl as what is being discussed in the thread. Text messages, call log, and some emails deleted literally nanoseconds after receiving them.

For those who think this is a memory problem, that is correct, however, not in the way you think. I have no ringtones, 3rd party apps, pictures, music, etc. on my phone memory. I do have a 2 GB microSD chip on which all such things are stored. I have deleted the sample video and music, deleted the unneeded language apps, and the bug still occurs. So telling people to stop downloading things to their phone is not the solution.

I have read on some other boards that the issue may be a "memory leak". I don't have enough knowledge to comment thoroughly on this, but it seems to be a software issue by which a program (or programs) causes the available memory to be used up unnecessarily over time. Once this buildup (or rundown) of memory reaches the critical level, the device just starts wiping out data. A "reboot" via removal of the battery "resets" the memory, but the problem returns after a few days when the buildup from the memory leak occurs again. Not sure if this really is the problem, but it's what I've read.

I have the T-Mobile v.64 of the OS, but have heard that people using all different sorts of OS and providers are having the problem.

This is a MAJOR RIM issue, and IMHO, makes their product wholly unsuitable for business use. How can RIM expect potential customers such as myself to use a device when clients may be sending me important emails or messages that I am not receiving because of thisbug ? Friends and family have been wondering why I'm not returning their messages! I've seen postings about this problem from as long ago as September, and have seen ABSOLUTELY NO RESPONSE OR ACKNOWLEDGEMENT from RIM or any of the service providers in any way. And that's what pisses me off the most. I'm at the point where my only option may be to return the phone and demand a full refund for breach of warranty.

Does anybody have any more information on this extremely important topic??? Thanks in advance for any additional info.

Re: Default all sms text & call log on 8100 disappeared! HELP!

Hey guys. I have been havinh the same issue with my pearl too. And I removed the battery to reset memory and also deleted pics and music to save up memory. The other day while at work on the computer it hit me. And till today my call log has been working the way its supposed to. My BB is not deleting any call logs or text messages any more. What I am doing and sure hope this helps, is I went to all programs and instead of exiting but hitting the back button, I clicked menu and selected close. On every thing I do on the phone, and till this very day at this very hour my call logs are not being deleted. I don't know how it worked. it was a hunch I had and its doing the job for me. It might not be much but its a temporary solution to a problem until RIM figures out a fix for it. Please let me know if It helped
